Answer:
9
Step-by-step explanation:
= x + 16° + x + 3° =5x - 8°[ Sum of two interior angles is equal to the exterior angle]
or, 2x + 19 = 5x - 8
or, 19 + 8 = 5x - 2x
or, 27 = 3x
or, x = 27/3
☆ x= 9

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?
Step-by-step explanation:
Store A:
6% of 1,200 is 72
72 + 1,200 = 1,272
Thus, store A has a total of 1,272
Store B:
7% of 1,350 is 94.5
94.5 + 1,350 = 1444.5
Thus, Store B has a total of 1444.5
1444.5 - 1,272 = 172.5
Thus, Store A is cheaper.
Answer:
sales tax- rate×original amount
A- 6/100(1200)=72
B- 7/100(1350)=94.5
2. An electric fan has a resistance of 3.0 kN and a voltage rating of 220 volts. What
is the current needed to operate the electric fan?
Given:
Resistance (R)
ka x (1000/1 kg) =
volts
Voltage (V)
Required: Current (1)
Formula:
voltage
resistance
Solution:
V-IR
Answer:
Current =
A, the current needed to operate
the electric fan
Answer: 73.33A
Step-by-step explanation:
Resistance (R)= 3.0 kN
Voltage (V)= 220 volts
Current (I)= Unknown
The formula to calculate the current will be:
Current = Voltage / Resistance
Current = 220 / 3.0
Current = 73.33 A
Therefore, the current needed to operate the electric fan is 73.33.

Answer:
y = x + 4
Step-by-step explanation:
Slope intercept : 2x - 2y = 8 = 2x 2x = 8 + 2y = 2x = 8 +2y = 2x-8 =2y is the sae as 2y = 2x -8 divide everything by 2 = 2x / 2 - 8/2 = 2y/2 = y = x-4
